Frozen culverts and sewer inlets were cleared to allow runoff from meltwaters and floodwaters.
As the ice continued to retreat, a series of east-west channels were cut by the easterly flowing glacial meltwater.
It was also possible to track the motion of fine-scale features in the surface geometry such as meltwater channels, and hence to determine the glacier's surface velocity, in some areas.
Nutrient rich lakes are found near the coast; sterile lakes are located further inland and are fed by meltwater and local precipitation.
The semi-automated method shows that reliable and consistent velocity vectors can be extracted from meltwater channels, and that these retain their identity over at least two years.
The interaction of contaminated sites with meltwater/groundwater and aeolian processes did not significantly change the hydrocarbon distribution at the former base site during the monitoring period (1992- 96).
However, we suspect that such nutrients are deposited from meltwater into impact-generated cavities, which would encourage endolithic heterotrophic bacteria to inhabit them.
They noted a strongly bisected coastline, with inlets reaching towards the ice cap, and numerous meltwater lakes, often without apparent external discharge.
